Revered planar technology

Planar magnetic technology is renowned for accuracy, response and control across the audible range.

The CL2 Planar is built around the smallest commercial planar magnetic driver ever released. A 16 micrometer-thin diaphragm and planar coil are suspended above two perfectly matched magnetic fields.

Four years in development, CL2 captures the precision, response and accuracy of planar magnetic technology, perfected for the first time in an in-ear driver – allowing for fully portable, high fidelity audio.

Refined, precise design

Injection moulded ceramic housings provide both low-distortion audio and a breath-taking aesthetic; coupled with the convenience of MMCX detachable connections. With applications ranging from synthetic diamonds to medical-grade implants, zirconium is an incredibly durable ceramic compound.

An injection moulding process – wherein the material is heated to over 1400°C in order to reinforce and purify it – is used to achieve the distinctive, precise shape on the interior and exterior. Using this process provides both a comfortable, unobtrusive fit and crystal-clear audio transmission.

Braided copper cable

Braided oxygen-free copper with a universal 3.5mm connection excels both at transmitting audio and resisting wear over time.

Silver-coated balanced cable

Silver-coated and full balanced, RHA's Ag4x cable ends in a 2.5mm connection.
